2008年7月，在亚北极峡湾多尔加亚湾(巴伦支海南部)，利用JUDAY网(网目尺寸为0.168 mm)对中游动物群落结构进行了研究。共发现39种及高等分类群。平均丰度、生物量和多样性(±标准差)分别为153,403 mg/m−，570 mg/m−，570 mg±661 mg干重，2.25±0.09 mg干重。桡足类是数量最多的物种。中游动物群落以杂食性动物(Oithona similis和Acartiaspp.)为主。各采样层中浮游动物的垂直分布以桡足类优势为特征。除平均生物量和平均水温呈负相关外，物理变量与生物学参数之间均无显著相关。
The community structure of mesozooplankton was investigated in Dolgaya Bay (southern Barents Sea), a subarctic fjord, using a Juday net (0.168-mm mesh size) in July, 2008. A total of 39 species and higher taxa were found. Average abundance, biomass and diversity (±standard error) were 153,403 ± 15,855 ind m−2, 570 ± 61 mg dry mass m−2, and 2.25 ± 0.09, respectively. Copepods were the most numerous species. The mesozooplankton communities were dominated by omnivores (Oithona similisandAcartiaspp.). Vertical distribution of the mesozooplankton was characterized by copepod dominance at each sampled layer. There were no significant correlations among physical variables and biological parameters, except negative correlation for the mean biomass and mean water temperature.
